Share your SQM?
I was just out closing up my observatory (3am here), and as the Seeing was particularly good for mid-summer, so I took a SQM reading: 20.85 . This is not far off my best ever recorded reading at my place on Lake Macquarie (20.92) which was from a few years ago. Increased development in the area has affected sky quality, but it is pleasing that on a good night it's still pretty good.
Have you noticed and recorded changes in sky quality at your place? What is acceptable to you?
